Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed November 6, 1906- Serial No. 342.189.

To all whom it may concern:

Be it known that I, FRANK W. OHAFFEE, a citizen of the' United States,and a resident of Albany, in the county of Albany and State of New York,have in vented certain new and useful improvements in Hose- Bands, ofwhich the following is a specification.

The invention relates to improvements in hose-bands, and it consists inthe novel features and structure hereinafter described, and particularlypointcd out in the claims.

The object of the invention is to produce a thoroughly durableandeflicient two-piece band for securing the end of hose to a coupling orferrule.

My invention pertains more particularly to hosebands of the characterrequired for securing the end of hose, used for air or steam, tohose-couplings, and especially for securing the ends of hose to theusual hosecouplings employed intermediate the adjoining ends ofrailway-cars.

I present my invention herein as embodied in a twopiece hose-bandemploying at the locking ends of the band the features described inLetters Patent No. 673,382 granted to me May 7, 1901 for an improvementin hose-bands.

The present invention resides more particularly in a novel constructionwhereby the band may be made in two parts capable of being jointedtogether in a hinged manner, the features of the hinge-joint being newand of great advantage and the band possessing them being adapted to beclosed around the hose without, at said joint, pinching and injuring thesame.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference be ing had to the accompanyingdrawings, in which:

Figure 1 is a side elevation of a piece of hose applied to ahose-coupling by means of a hose-band constructed in accordance with andembodying my invention; Fig. 2 is an enlarged detached side elevation ofthe hoseband, the two parts thereof being shown as jointed together;Fig. 3 a perspective view of same; Fig. l a vertical transverse section,through the hose and band, on the dotted line 4-4 of Fig. 1, and Fig. 5a detached edge view of the band.

the hose band is in use to receive the outer wall 14 of the opening 15formed in the head 16, which is upon the outer end of the member 8.

The tongue 11, lug 12, opening 15 and head 16 are substantiallyidentical in construction and operation with corresponding featuresshown in my Letters Patent dated May 7 th, 1901 and are not separatelyclaimed herein; nor is the present application limited to the saidspecific interlocking features for securing the band upon the hose.

The inner end of the band-member 7 is formed with a tongue 17 and lug18, the latter projecting centrally from the outer face of the inner endportion of said memher 7 and being less in width than said member andcarrying upon its opposite faces studs 19 which extend transversely ofthe band and together form, in effect, a transverse pin.

he member 8 of the hose band is formed at its'inner end with the concaverecess 20 to receive the lower convex surface of the tongue 17, asindicated more clearly in Fig. 4, and said end of said member 8 isbifurcated to form the lingers 21 which straddle the lug 18 and arecurved, as at 22, to pass upon and partly around the studs 19 and becomehooked thereon.

In assembling the two parts of the band the member 8 is turneddownwardly so that its inner end may be uppermost and the fingers 21 arethen passed upon the lug 18 between the body of the member 7 and pins19, and thereupon said fingers are worked inwardly around the studs 19and the member 8 gradually turned upwardly on the are of a circle struckfrom said studs, until the members 7, 8 assume their band-like relationto each other. When the band is securely clamped around the hose and atits outer ends locked together by the depression of the head 16 over thelug 12 and the engagement of the wall 14 with the wall of one of therecesses 13, the interior of the band presents a substantially smoothsurface owing to the fact that the tongue 17 sets within' the recess 20,as shown in Fig. 4, and at this time, the curved lingers 21 bear withtheir upper surfaces against the outer inner end portion of the member 7and also against the outer sides of the studs 19, whereby the two partsof the band become securely fastened together.

"he present invention resides more particularly in the constructionprovided at the inner ends of the members 7, 8 for conveniently andeffectually connecting said ends, and the construction I have herein--before described for that purpose is particularly durable and efficient,as is required owing to the uses to which the hose-bands are put intheir employment on railway cars. The presence of the tongue 17 on theaforesaid member 7 and the recess 20 on the member 8 enables theproduction of a smooth interior surface in the band for engagement withthe hose, and the fact that the tongue 17 extends beyond the lug 18 soas to lap upon the member 8 beyond the axial hinging point of themembers, is important in that by reason thereof I avoid the creating ofabutting surfaces at the hinge liable to pinch the hose between themwhen the said members are closed tightly together. In the presentinstance the member 7 is fitted against the hose, and the application ofthe member 8 is by reason of the hinge construction presented, in anupwardly direction and substantially in a direct radial line against thesurface of the hose, whereby there is no tendency to pinch the hose atthe line where the inner end portions of the bandmembers 7, 8 engageeach other. The lug 18 and studs 19 are integral with the member 7 andthe fingers 21 are integral with the member 8, and said fingers 21extend outwardly from the band, whereby they are enabled to resistextreme internal pressure said fingers being secured between and bearingagainst the studs 19 and outer surfaces of the member 7 at oppositesides of the lug 18.

The construction as a whole has been produced with the view of securinggreat durability and efficiency and convenience in applying the membersof the band to each other and to the hose.

\Vhat I claim as my invention and desire to secure by Letters-Patent,is:

1. A hose-band comprising parts 7, 8 having at their outer endsrespectively rigid integral locking members for firmly locking one ofsaid ends upon the other and at their inner ends means for connectingsaid parts together and comprising on one part a tongue 17 and outwardlyprojecting lug 18 having transverse studs 19 and on the other part arecess to receive said tongue and fingers 21 to straddle said lug andpass upon and engage said studs;

substantially as set forth.

2. A hose-band comprising parts 7, 8 having at their outer endsrespectively rigid integral locking members for firmly locking one ofsaid ends upon the other and at their inner ends means for connectingsaid parts together and comprising on one part a tongue 17 and outwardlyprojecting lug carrying a transverse pin and on the other part a recessto receive said tongue and a curved' part to pass between said pin andits band member and extend outwardly in hook fashion from the band andalong the outer side of said pin; substantially as set forth.
